Transfer of flats

Dear Sir We are 4 siblings together and our Mother expired on 2015 and we gave a n application to the society, regarding the transfer of the flat on my name with all the papers prepared by an advocate regarding bye laws section 35, 17 & 19 form 4 4c etc. all sets of paper were given to them in 2016 and till date they have not transferred the property on my name. Now they are asking for some registered documents from the registration office on which they say we will do the transfer or succession certificate. As our financial condition is weak we are not able to do anything,,, i also visited the registration office the officer said that we can't register the affidavit and the society can do the transfer on papers which i made through the advocate My question...... 1. is the bye laws 35, 17 & 19 invalid? 2. Can they do the transfer on the that papers? 3. why they need succession certificate as there is no dispute between the heirs? 4. What is the simple procedure in which no time is consumed? 5. what action needs to be taken against the society? Santosh Padani Mumbai
